Existing vehicle alternator control device using exciting current value is not controlled and only by voltage control system
Carry out voltage-controlled structure, and the control device of the vehicle alternator in the embodiments of the present invention 1 shown in Fig. 1 is adopted
With the structure of the control function added with exciting current value.
ECU is that external unit 7 detects the running status of internal combustion engine, the state of mechanical load, the charging of on-vehicle battery 22
State of state and electric loading 22 etc., and calculate the benchmark excitation of vehicle alternator 1 based on these testing results etc.
Current value, the external command a corresponding to the above-mentioned benchmark exciting current value calculated is sent to outside generator control unit 2
Portion's instruction reception portion 8.A is instructed for example by pwm signal structure from the said external that external unit 7 is sent to generator control unit 2
Into.The pwm signal possesses dutycycle DUTY (DUTY=t/T corresponding with the benchmark exciting current value；T is the height of pwm signal
During level, T is the cycle of pwm signal).In addition, external command a can also be made up of the signal beyond pwm signal, say below
Situation about being made up of pwm signal is illustrated in bright.
External command/exciting current indicated value converter section 90 in generator control unit 2 is by the institute of external command acceptance division 8
The external command a received is converted into exciting current indicated value b.Fig. 2 is to represent automobile-used involved by embodiments of the present invention 1
Relation between external command a and exciting current indicated value b in the control device of alternating current generator, be made up of pwm signal
Mapping explanation figure, transverse axis is denoted as the dutycycle (%) of external command a pwm signal, and the longitudinal axis represents that exciting current refers to
Indicating value b (A).
In Fig. 2, when the dutycycle of pwm signal is more than 10 [%]~be less than 90 [%], the dutycycle and excitation of pwm signal
Current instruction value b is proportional, exciting current indicated value b to it is more than dutycycle 10 [%]~be directly proportional less than 90 [%] as 0A
~7.5A.On the other hand, dutycycle is that more than 0 [%]~scope D1 less than 5 [%] is assumed that from external unit 7 and is connected to hair
The scope during failures such as broken string occurs for the external command transmission of motor control assembly 2 wire harness, and dutycycle is more than 5 [%]~small
In 10 [%] scope D2 and more than 90 [%]~be less than 95 [%] scope D3 be for absorb pwm signal waveform miss
The scope of difference, more than 95 [%] scope D4 assumes that the scope of earth fault etc. occurs for the external command transmission wire harness.
In scope D1, D2 of above-mentioned dutycycle, exciting current indicated value b is exciting current instruction in 0 [A], scope D3, D4 of dutycycle

Controlling value d.
Voltage control division 6 is obtained detected by target voltage values e and voltage detection department 4 from target voltage instruction unit 10
Vehicle alternator 1 output voltage values f between deviation, generate for the voltage controling value that makes the deviation be changed into " 0 "
g.The conduct that target voltage values e produced by target voltage instruction unit 10 turns into as described later is judging external command a for nothing
The controlling value of failure safe value during effect, be for example set equal to on-vehicle battery 22 rated output voltage value or slightly above
The magnitude of voltage of the value.
External command invalidating judging part 11 judges that the external command a received by external command acceptance division 8 is effective
Or it is invalid.According to the dutycycle of the pwm signal as external command a with the presence or absence of the scope D1 or model shown in above-mentioned Fig. 2
Enclose in the range of D4 to carry out the judgement, if for example, the dutycycle of pwm signal is present in scope D1 or scope D4, as above
It is described, due to assuming that for be connected to generator control unit 2 external command transmission wire harness occur broken string etc. failure or
The situation of earth fault etc. occurs with wire harness for external command transmission, therefore be judged as that external command a is invalid, and if pwm signal
Dutycycle is not present in scope D1 or scope D4, then is judged as that external command a is effective.
Selector 12 is in the case where the judged result of external command invalidating judging part 11 is " effective ", and selection comes
The exciting current controlling value d of self-excitation current control division 17, and PWM control units 5 are supplied to, in the feelings that judged result is engineering noise
Under condition, the voltage controling value g from voltage control division 6 is selected, and be supplied to PWM control units 5.PWM control units 5 are based on selector
The exciting current controlling value d from exciting current control unit 17 selected by 12 or the voltage control from voltage control division 6
Value g, PWM controls are carried out using switch element 15 to exciting current value.
In the control device of vehicle alternator in embodiments of the present invention 1, sentence in external command invalidating
In the case that disconnected portion 11 judges the external command a provided by external command acceptance division 8 as " effective ", selector 12 is selected by excitation
The exciting current controlling value d that current control division 17 is generated, and it is supplied to PWM control units 5.PWM control units 5 are based on by excitation electricity
The exciting current controlling value d that flow control part 17 is provided determines dutycycle that the conduction and cut-off of switch element 15 is controlled, and provides
Base stage to switch element 15.As a result, exciting current value c be controlled so as to it is consistent with external command a.Therefore, in outside
In the case of instructing a constant, exciting current value c is controlled so as to keep constant.
There is the relation being relative to each other in exciting current value, with the rotating torques of vehicle alternator if therefore known automobile-used
The rotating speed and exciting current value of alternating current generator, then can extrapolate the rotating torques of vehicle alternator 1.As described above, structure
Exciting current value that can be directly to vehicle alternator 1 into the ECU of external unit 7 is controlled.ECU is by knowing excitation electricity
Flow valuve can correctly grasp the rotating torques of vehicle alternator 1, and ECU can control automobile-used friendship by controlling exciting current value c
Flow the rotating torques of generator 1.
As described above, the control device of vehicle alternator according to embodiment 1 of the present invention, can be based on excitation
Current value grasps the rotating torques of vehicle alternator 1, so that control exciting current value c, therefore in the idle running of internal combustion engine
Generator will not be caused to stop during operation etc., stabilisation, the improvement of fuel consumption of internal combustion engine control can be greatly facilitated.
If in addition, external command invalidating judging part 11 is judged as that the outside for providing to come from external command acceptance division 8 refers to
It is engineering noise to make a, then selector 12 selects the voltage controling value g of voltage control division 6 to be supplied to PWM control units 5.Thus, PWM
Control unit 5 determines the dutycycle of the conduction and cut-off control of switch element 15 based on the voltage controling value g of voltage control division 16,
And it is supplied to the base stage of switch element 15.As a result, vehicle alternator 1 is controlled so as to and target voltage instruction unit 10
Target voltage values e is consistent.
Therefore, even if because certain is former so that the external command a from external unit 7 is changed into abnormal, but due to switching
To the voltage control system being made up of as described above voltage detection department 4, voltage control division 6 and target voltage instruction unit 10, because
This, can also prevent overvoltage, without great functional faults such as generatings.
